A hydroprocessing bulk catalyst is provided. A process to prepare the hydroprocessing bulk catalyst is provided. The hydroprocessing catalyst has the formula (R)(M)(L)(S)(C)(H)(Oy)(N), wherein M is at least a "d" block element metal; L is at least a "d" block element metal different from the "d" block element metal M; t, u, v, w, x, y, z represent the total charge for each of the components (M, L, S, C, H, O and N, respectively); R is optional and in one embodiment, R is a lanthanoid element metal; 0≤i≤1; pi+ta+ub+vd+we+xf+yg+zh=0; 0<b; 0<b/a≤5; 0.5(a+b)≤d≤5(a+b); 0<e≤11(a+b); 0<f≤7(a+b); 0<g≤5(a+b); 0<h≤2(a+b). The catalyst has an X-ray powder diffraction pattern with at least three diffractions peak located at 2-θ angles of greater than 25°. In one embodiment, the catalyst is prepared by forming at least one sulfided catalyst precursor from at least two "d" block element metals; and mixing the catalyst precursor with a hydrocarbon compound to form the hydroprocessing catalyst composition. In another embodiment, the catalyst is prepared by the thermal decomposition of an oil dispersible sulfur containing organic metal precursor upon contact with a hydrocarbon oil, generating a slurry catalyst. In yet another embodiment, the catalyst is prepared from an in-situ or ex-situ sulfidation of "d" block element metal precursors in a solvent carrier. |
